Scientists discuss why we might not spot solar panel technosignatures

Conceptual image of an exoplanet with an advanced extraterrestrial civilization. Structures on the right are orbiting solar panel arrays that harvest light from the parent star and convert it into electricity that is then beamed to the surface via microwaves. The exoplanet on the left illustrates other potential technosignatures: city lights (glowing circular structures) on … Read more

Coinfecting viruses obstruct each other’s cell invasion

Coinfecting viruses obstruct each other’s cell invasion

The first author Thu Vu Phuc Nguyen, left, and Ido Golding investigated how coinfecting phages can impede each other’s entry into a cell. Credit: Fred Zwicky The process by which phages—viruses that infect and replicate within bacteria—enter cells has been studied for over 50 years. In a new study, researchers from the University of Illinois … Read more

Improving cat food flavors with the help of feline taste-testers

Improving cat food flavors with the help of feline taste-testers

Credit: CC0 Public Domain Cats are notoriously picky eaters. But what if we could design their foods around flavors that they’re scientifically proven to enjoy? Researchers publishing in ACS’ Journal of Agricultural and Food Chemistry used a panel of feline taste-testers to identify favored flavor compounds in a series of chicken-liver-based sprays. The cats particularly … Read more

Study yields new insights into the link between global warming and rising sea levels

The ANET-POLENET team flew to remote field sites on Antarctica’s Backer Islands to record bedrock uplift. Ohio State University co-author Terry Wilson is second from the left.

Scientists pin down the origins of the moon’s tenuous atmosphere

Scientists pin down the origins of the moon’s tenuous atmosphere

Credit: Unsplash/CC0 Public Domain While the moon lacks any breathable air, it does host a barely-there atmosphere. Since the 1980s, astronomers have observed a very thin layer of atoms bouncing over the moon’s surface. This delicate atmosphere—technically known as an “exosphere”—is likely a product of some kind of space weathering. But exactly what those processes … Read more

Venus’ ‘continents’ suggest surprising link to early Earth

Computational simulation of Venus-like mantle convection. Credit: Nature Geoscience (2024). DOI:10.1038/s41561-024-01485-3 New research has revealed that Venus, often considered Earth’s inhospitable twin, may share a surprising geological history with our own planet. Scientists have discovered that Venus’ vast plateaus, known as tesserae, may have formed through processes similar to those that created the Earth’s earliest … Read more

Tuariki Delamere’s Somersault Could Have Launched a New Era in the Olympic Long Jump

Tuariki Delamere’s Somersault Could Have Launched a New Era in the Olympic Long Jump

However, since this force is applied at the feet, far from the center of mass (r > 0), it’s going to produce a torque. In this case, the torque would cause a forward angular acceleration, tending to deposit the jumper face down in the sand. So athletes use a few different techniques to counter this … Read more
